What is the benefit of the Spec-37 iron alloy used in these rotors?

The proprietary Spec-37 iron alloy is specifically formulated to withstand extreme braking temperatures. It offers a high degree of resistance against common issues like distortion, warping, cracking, and wear, ensuring a longer service life under demanding conditions.

What does the black e-coat finish do?

The black e-coat finish on these GTB rotors is applied for improved corrosion resistance. This helps protect the rotor surface from rust and environmental damage, especially in areas with high moisture or road salt exposure.

What is the purpose of the curved vane design and slot pattern?

The 60 curved vanes are designed to maximize airflow through the rotor, providing superior cooling capacity. The asymmetrical face slot pattern helps to sweep away brake dust and gases from the friction surface, which leads to more consistent and reliable braking performance, especially during hard use.

Product Details

Wilwood's GT60 Curved Vane rotors are built using their proprietary Spec-37 iron alloy, a material developed to handle extreme temperatures and resist distortion, warping, and cracking. This alloy is derived from technology used in Wilwood's military-spec rotors, meaning it's made to stand up to serious abuse. The GTB version, like this one, also gets a black e-coat finish to help fight off corrosion, which is a nice touch if your vehicle sees a lot of road salt or moisture.

These rotors feature Wilwood's GT Series asymmetrical face slot pattern, which helps clear dust and gas away from the braking surface for more consistent stopping power. They're also dynamically balanced to ensure a smooth, vibration-free performance, no matter how hard you're braking. The 60 curved vane design offers excellent cooling capacity, making them a solid choice for demanding track use or any situation where you need maximum braking performance and longevity.

This rotor measures 15.50 inches in diameter and is 1.38 inches thick, with a bolt circle of 12 on 10.25 inches. It's designed for applications where extreme braking is a regular occurrence, providing the cooling and durability needed for competitive driving or heavy-duty use.
